   I'm reminded of the work that was done to reverse engineer the Intel ME 11 [1], it was compressed with an unknown Huffman code which the team was nevertheless able to recover somehow. And that was with variable-length words! [1] http:

   Sorry about that, it works OK on my iPad and in the iOS simulator, if you want to help me debug your system drop me a line!

   Thanks! A big part of the idea is representing data flow, I don't think that makes as much sense with a concatenative language where things are irregularly moving on and off the stack. You'd have to show the relation of words to t

   Good catch, it shouldn't be possible to drag the white sqaures ("handles") any direction but up.

   Thanks! There's no real optimization, everything is just done from the bottom up: a box is large enough to contain its rows, rows are large enough to contain their "cells" (which are just the boxes the next level down). There

    If you want to use it now I can slap on whatever license you'd like, it's just a first test so I haven't thought about the "real thing" yet.

    I've got a fairly large example [1] in place now, 128 nodes directly under the root, it is the proof assistant from The Little Prover [2]. I hacked at this a bit to get the framerate usable. Make of it what you will, I find it neat but

    Thanks! If you can point me to a good structure I'd like to try coding it up in this system, category theory has mostly gone over my head so I'm not sure what you're thinking of. If it's large I might finally have to sta

    Testing with more nodes is definitely on the horizon, that's the main reason for the zoom (besides being visually interesting). Can you suggest a good data set? You may have to tap on the text box to get the edit to work and engage you

    Coincidentally I just started working on an editor for touch screens that relies on displaying nesting like this. I also worked on a syntactic zoom which I'm sort of proud of, but don't know how practical it could be yet. Editing

    Interesting, so many analyses of these structures! One more that I don't think was reachable from the article is on the blog These Heterogenous Tasks: https://heterogenoustasks.wordpress.com/2015/01/26/st

    I don't see why "having to settle for macrostates" is anything more than the observation that we use heuristics. Maybe because I don't understand your statement "our brains and bodies do have an artificially imposed

    I suspect the important point is that rotations cycle around (keep rotating and you come back to where you started)

    Miegakure did something similar where it showed a shadow of the 3D space immediately adjacent to the currently visible slice. I think he since removed that, so I expect he must have experimented with something similar in 4D Toys and decided

    Very interesting, thank you! The father (Mark Engelberg) also designed a mass-market programming board game/puzzle, Code Master [1], which seems neat. I just grabbed a copy at Target. [1] http://www.thinkfun.com/product
